DC Multi-function Energy Meter PZ72L-DE
PZ series intelligent DC energy meter is designed for applications such as DC panels, solar power,telecommunications base stations, and charging posts. This series of instruments can measure voltage, current, power,forward and reverse power in DC system. It can be used for local display, and connected with industrial control equipment, computers, form a measurement and control system. And it has a variety of external excuse functions for the user to choose: RS485 communication interface, Modbus-RTU protocol, relay alarm output, digital input/output.According to different
requirements, through the instrument panel keys, you can set the ratio, communication parameters.
The product meets the relevant technical requirements of the standard Q/GDW1825-2013 DC power meter specification，GB/T29318-2012 Non-vehicle charging electric energy metering for electric vehicles，Q/GDW364-2009 Single-phase energy meter specification.
